KILN HAVING SUPERPOSED CHAMBERS FOR CONTINUOUS WORKING.

SPECIFICATION forming part of Letters Patent No. 635,513, dated October 24, 1899.

Application filed May 4, 1899. Serial No. 715,591. (No model.)

To all, whom it may concern.-

Be it known that 1, PAUL SOHLEIOH, a subject of the King of Prussia, Emperor of Germany, residing at Hohenneuendorf, Mark, Germany, have invented certain new and useful Improvements in Kilns Having Superposed Chambers for Continuous WVorking, (for which I have applied for a patent in Germany, and which application is dated December '7, 1898,) of which the following is aspecification.

This invention relates to double-storied.

kilns for burning glazed tiles, facing-stones, and fine potteries; and it has for its purpose to light and keep up in the lower chambers by a suitable admission of the heating-gases a uniform choked fire to lead the gases from the lower chambers in a suitable manner into the upper chambers, which can be shut off at will, and where the gases may be employed for burning finer potteries, which cannot suffer so high temperatures. There are, more: over, means provided by which the gases can be led from the upper chamber into peculiar drying-rooms, either for drying preparatorily the material to be burned arranged above the kiln or into the fireplace of the following chamber to be heated or directly into the chimney.

The accompanying drawings show a plant according to this invention, and with reference thereto I shall explain hereinafter the.

construction and manner of working of the kiln.

In the accompanying drawings, Figure 1 shows a vertical sectional view of the kiln. Fig. 2 is a cross-sectional view showing a modification. Fig. 3 is a horizontal sectional view of the same.

As represented in the drawings, the plant consists of a certain number of pairs of chambers A A B B O 0, arranged one beside the other. In the drawings there are provided three pairs of chambers. In front of each lower chamber, nearly at the same height as the sole, are the fireplaces D D D. In each lower chamber A B 0 near to the inlet-passage of the heating-gases there is arranged a breast-wall E E E", extending up to a certain height and provided at the lower end with a limited number of passages F F F. The arrangement of these breast-walls provided with the said passages has only for its purpose to distribute the gases flowing from the fireplaces into the burning-chambers uniformly through the material to be burned.

As taught by experience, the plants hitherto known offer the drawback that inlighting and keeping up a stified fire in only one direction the material touched first by the gases is burned through too much, and then the gases 011 their passage through the material piled up are cooled to such an extent that the layers coming last in contact with the gases receive too little heat, so that an irregular burning will take place. In the plant making the object of this invention these drawbacks are avoided in the following manner: In the soles of the chambers A B 0 there is arranged a number of passages a b 0, leading the gases through branch channels into the collecting channels G G G" and thence through the channels H H H to the chambers A B 0, arranged above the chambers A B O. The gases fiow here from the passages d e from below upward through the material contained in the said chambers, and they escape through the channels 9 h z' from the upper chambers.

As already mentioned, the gases may be led either directly through the collecting-channels K K K to the chimney or through the channels g h 1', covered by plates 19, to the drying-rooms above the'kiln, and they may be used here for drying preparatorily the material piled up there.

In order to obtain a rational and economical working, there are ,still provided auxiliary channels and regulating-slides, by means of which the working can be rendered continuous, the chambers to be cooled being closed and shut off from working after the material has been burned. This is in particular advantageous when the material is sensitive against the direct cooling process, and

for this reason it is necessary to let it stand In the channels L M there are arranged, moreover, the slides O O P P for the purpose hereinafter explained. The smoke collecting channels K K K, leading to the chimney, are in communication with the channels L M N through the slides Q Q Q, and this communication can also be shut off. \Vhen the plant is normally working and all the chambers are in full fire, all the fireplaces D D D are charged. The gases flow then from the fireplaces into the chambers for the larger part through the channel formed by the breast-wall E and the chamber wall from above upon the material to be burned. For the smaller part they are led through the passages F F F, arranged in the breast-wall, to thelower layers of the material. From thence the gases pass through the channels H H II and the passages d ef to the upper burningehambers A B C, flowing therein from below upward.

To utilize the gases of the first chambers for the working of the following ones, they are led from A through the channel L, the slide of which is opened and the branch channel L shut off by the slide R below the sole of the kiln to the fireplace D of the chamber B. Flowing through the channel L the gases have taken up already a large amount of the heat given 01f from the chambers of the kiln to the masonry, so that they pass nearly at the same temperature with which they enter the chamber A through the grate into the fireplace D, where they are heated anew. In the further course the gases pass nearly the same way as above described, and finally they enter the chamber being at work, (in the drawings the chamber C,) from which they are led either through the smoke-collector K to the chimney or through the ehannelsi 't' to the drying-room. In the working above described the slides P P are opened and Q, Q closed.

To stop the kilns B and O and to let them stand in afterglow, but to maintain at work the chambers A, 15, and C, it is merely necessary to close the slides O P and O P and to open R R and U U. The heating-gases produced in the fireplace D ilow then in the following manner: The gases after having passed from above downward through the material piled up in the chamber A flow first through the channel II into the chamber A, through the channel L, L, and II, and the openings 0 c to the second upper chamber B, the material of which is passed through by the gases in the same manner from below upward. From thence the gases fiow through branch channels 7t 7t, channels M, M, and H,

and passages f into the chamber 0. As already mentioned, the gases can be led thence directly through the smoke-collectors K and the main collecting-channel Z, Figs. 2 and 3, to the chimney or through the branch channels i i to the drying-room arranged above the kiln and used there for drying preparatorily the material piled up there. As shown in Figs. 2 and 3, there is provided beside the series of chambers A B C A B C a second series of chambers A B C A B O,, the arrangement and manner of working of which are exactly the same as first described. The laterally-arranged channels K K Fig. 2, have for their purpose to lead over the heating-gases of the last chamber of the first series under the fireplace of the first chamber A of the second series, whereupon they pass again in the same manner as above described. All the heating-gases flow,after having passed through the whole plant, through the channel Z into the chimney.

The stopping and setting to work of the chambers of the two series can be elfectuated by means of this arrangement as may be desired, and it ofifers the advantage to utilize in an exhaustive manner the heating gases, while at the same time the material piled up in the several chambers is thoroughly burned with certainty.

I claim The combination in a kiln, the superimposed chambers arranged in series, a passage leading from the fireplace of the lower chamber of the first series to the upper part thereof, openings leading through the floor of said chamber, apassage-way leading from beneath said floor in communication with said openings to a point below the floor of the upper chamber, openings leading through the floor and through the top wall of said chamber and a passage leading from above said upper chamber in communication with said latter openings to the fireplace of the lower chamber of the second series, a passage leading from the lower chamber of the second series to the upper chamber of said series and a branch passage connecting said passage with the passage leading from the upper chamber of the first series and valves arranged in said passage-ways, substantially as described.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

PAUL SCI'ILEIGII.
